What' is genetic engineering List the steps in rDNA technology.

Explanation

### Step-by-Step Solution:

1. **Definition of Genetic Engineering**:
Genetic engineering is a technique that allows for the alteration of the genetic material (DNA or RNA) of an organism. This process enables the introduction of new genetic material into a host organism, resulting in changes to its genotype (genetic makeup) or phenotype (observable traits). It is utilized for various applications, including improving agricultural crops, developing medical therapies, and producing genetically modified organisms (GMOs).

2. **Steps in Recombinant DNA (rDNA) Technology**:
- **Step 1: Isolation of DNA**: The first step involves extracting the DNA from the organism of interest. This is typically done using chemical or physical methods to break down cellular structures and release the DNA.
